Nonwireline and wireline carriers are assigned separate blocks of frequencies, as are cell sites, and cellular units. See also BAND.
Consists of a specific, pre-determined number of bytes. Block sizes vary, but a block size of either 512 or 1024 user data bytes is commonly used.
in message transfer, a physical division of a message (a complete unit of communication). NOTE-In SECS-I, each block has a block header (a 10-byte data element used by the message and transaction protocols) and up to 244 bytes of data. For compatibility with SECS-I, SECS-II also recognizes the same block length for data; however, in SECS-II there is only a message header, not a header for each block.

A block may also specify storage allocation or segment programs for other purposes.
In computing (specifically data transmission and data storage), block size indicates a nominal size, usually expressed in bytes or bits, of a block of data. Data thus structured is said to be blocked. The process of putting data into blocks is called blocking.
